"Introduced my opponent to Catch Wrestling by strapping on a double wrist lock in the 1st round," Jacobs posted on his Facebook page Saturday.

Jacobs, a two-time NCAA championships qualifier for the Spartans, gave up six inches on the 6'3" Hawkins.

"He had reach and he's very wild and reckless, throwing bombs," Jacobs told InterMat. "(He) came in swinging, took a hard shot and went for the takedown. He scrambled up and then he landed a nice knee right in my nose. I took him down immediately and strapped on the double-wrist lock."

"I was extremely happy to showcase catch wrestling in an MMA setting."

It was the second win for Jacobs, 28, in his amateur MMA career.

Jacobs teaches catch wrestling at Murcielago MMA, one of the top MMA programs in Michigan.
